To all whom it may concern:

Be it known that I, GERALD Boni-iorn, citizen of the Swiss Confederation, residing at Basel, Switzerland, have invented a new and useful Improvement in Triazine Azo Dyestuffs, of which the following is a full,v

in water, dissolving in sulfuric acid so lutions with bluish-red to violet-blue oolora:,- tions, in alcohol to orange-red to brown-red, in glacial acetic acid to more or less Violet red solutions. The new dyestuffs may be employed for the manufacture of lakes but they are especially Valuable for the prodiie 7, tion of fast tints on the fibre. Owing to a" certain aflinity of the above mentioned olerivativesof the 1.3.5-triazine for cotton the material prepared with these products need not be dried before treating it with these diazo c0mpounds. vary from yellowish-red to blue and black; they are fast to washing and maybe fast to light and chlorine. f

The yarn after having been well boiled and dried, is impregnated with a solution containing 20 gr. of QA-fitri-para-hydronynaphthyl-l.3.5-triazine, 15 cc. of caustiosodu at solution of 30% strength and 20 cc. of Turkey red oil per liter. The material is thoroughly wrung out and immediately passed through a bath of diazotized fc-ClfllOIO- 2 amiuobenzol 1 phenylether, neutralized at with sodium acetate. The yarn is thus dyed full fast Bordeaux tints.

. The new dyestufi' corresponds most probably with the following formula:

The black dyestuff obtained with 4: amino 2 methoxyphenylazonaphthalene (of; table) dissolves in concentrated sulfuric acid with violet-blue, in alcohol with brownish-orange and in glacial acetic acid with red coloration.

The new dyestufl corresponds most probably with the following formula:

Cotton is prepared with an alkaline solution containing 20 'gr. of 2.4-di-para-hydroxynaphthyl 6 (5-hydr0xynaphthyl-1.3.5 triazine and then passed through a bath of 4.4:-tetrazo-3-methoxy-6-methyl azobenzene neutralized with sodluni acetate. The cotton is thus dyed full black tints.

Cotton is prepared with an alkaline solution containing gr. of 2.4-diainin0-6-parahydroxynaphthyl-1.3.5-triazine and passed through a bath of diazotized 4-chloro-2- a black powder dissolving in concentrated sulfuric acid with Violet-blue in alcohol ,yzith red and in glacial acetic acid with bluish-red coloration.

The exact formula of the new dyestuff is not known but it contains most probably the atomic grouping:

aminobenzol-l-benzylether. The cotton is thus dyed full bluish-red tints.

The dyestufi' prepared in substance forms 'a dark powder, dissolving inconcentrated sulfuric acid with bluish-red, in alcohol and glacial acetic acid with red colorations. The dyestufi in which the two amino residues of the triazine nucleus have been substituted by two pheux laniino residues has analogous properties The dyestufi obtained by uniting l-chloro-o-anisidine with 2.4-di-para- XVhat I claim is: 'nnrwt'a 'tnrc of new dyestuffs by treating 1.
